I'm on business http://unitech.vn/atosmedicalpl-75ea.pdf#annoyance grand-med.pl Moser and his group at Western's Zircon & Accessory Phase Laboratory (ZAPLab), one of the few electron nanobeam dating facilities in the world, determined the growth history of crystals on a polished surface of the meteorite. The researchers combined a long-established dating method (measuring radioactive uranium/lead isotopes) with a recently developed gently-destructive technique at UCLA that liberates atoms from the crystal surface using a focused beam of oxygen ions.
